Data
Assimilation merges observations & model predictions
to provide a superior state estimate.
Remotely-sensed hydrologic state or storage observations (temperature,
snow, soil moisture) are integrated into a hydrologic model to improve prediction, produce
research-quality data sets, and to enhance understanding of
complex hydrologic phenomenon.
